Here we go, one quick test. I start xscanimage as normal user. It
doesn't ask me what device I want to choose (like it does for root),
it uses the net:localhost:plustek_pp:parport0 automatically. I click
"Preferences" in the menu and check the checkbox "Show advanced
options": xscanimage disappears without saying "Good bye".
I try again, xscanimage comes up, I make the window a little bit
larger --> Preferences --> Show advanced options. Ooops, it really
shows me these options: 4 range sliders in the righthandside part of
the window. I click on the slider "Bottom-right y [mm]". Again it
doesn't say "Good bye". Remarkable, when I start xscanimage as root
I can play with the sliders, but when I click on "Preview window",
it crashes with an error message:
"xscanimage konnte nicht als Anwender root ausgeführt werden:
Unterprozess endete mit dem Status 13"
Whatever that means, German is my mother tongue, but this message
tells me nothing.
So far for this evening.

Sorry, do you mean the CVS-version of the backend? I have very
little experience in compiling stuff from source. Or do you mean
backend+sane+scanimage+???
I guess, I'll learn a lot this week.

There is no /dev/parport0 here, all I have is a /dev/port or
/dev/.static/dev/parport0. But anyway, what should I do to make it
available for normal users, if there would /dev/parport0 exist,
chmod o+rw?

Again, I guess, I'll learn a lot this week.

It was just some luck combined with a lot of masochism. That's the
way how we live together with computers today, isn't it?
